Teething usually begins between 4 and 7 months and can be a frustrating time for both baby and parent. The infant may drool more and want to chew on things, and this is likely to be upsetting and the baby will be more irritable. To alleviate these symptoms, baby needs something to chew on, and if it's cold, all the better. It is a cool teether, very easy to hold, available in various colors and textures to massage the gums, containing sterilized water, which when cooled in the refrigerator will soothe baby's teething symptoms. In addition, this model has a clip to hang it on baby's clothes and other places, to prevent the teething area from getting lost or falling on the floor.
